Leica has released a new Firmware for the Leica M10 that provides a bug fix for SD card compatibility. We had several M10 users bring to our attention that the M10 had some issues with certain SD cards. Leica has now fixed this issue with the most current firmware release.

Of course, we still recommend using the highest quality card in your M10. Either UHS I or UHS II cards will work in the Leica M10. It is imperative that you use a card that writes at least at 80mb/s. This will allow the camera to process files efficiently, and offload the buffer during shooting. Without a card that writes at fast speeds one could experience degraded camera function during use.
